Use this screen to specify the protocols and routing/bridging options supported on this LAN interface.
The protocols and routing/bridging options you specify here must be identical to those configured on the other side of this LAN interface (that is, on the peer system).
You can enable one or more of the protocols listed (TCP/IP, IPX, or Other). Other means any protocol other than TCP/IP or IPX. Use Other if you intend to run SNA protocols over this LAN interface.
There is slightly less overhead if you use routing encapsulation. Therefore, the only reason to use either type of bridging is if the peer is limited to bridging or if you are using protocols other than TCP/IP or IPX.
